[LTP] [RFC PATCH v3 2/5] tst_test.sh: Introduce TST_NO_DEFAULT_RUN

[Cyril Hrubis <chrubis@suse.cz>]

Hi!
> TST_NO_DEFAULT_RUN is somehow similar to TST_NO_DEFAULT_MAIN. It's meant
> to be used for libraries and tools using tst_test.sh. It helps to use
> part of test framework functionality without wanting to run test.

I guess that we may want to initialize the TST_ID, LTPROOT and
TST_DATAROOT regardless, otherwise this looks pretty much
straighforward and okay.
